Dwyer Instruments A3002 Pressure Switch/Gage 320735-701 Due to the modular Sporlan

Due to the modular Sporlan A8 architecture

this valve provides precise thermostatic control and integrated ignition supervision

This cable is rated for indoor plenum environments

It is commonly used in oil-fired burner systems where consistent combustion air delivery is critical for ignition stability and heat output

typically functioning in a constant torque or X13-style capacity depending on the specific York unit's logic

Dwyer Instruments A3002 Pressure Switch/Gage 320735-701 Due to the modular SporlanThe Dwyer Instruments A3002 Pressure Switch Gage is a high precision, 3 in 1 instrument designed for the simultaneous measurement and dual limit control of differential pressure, positive pressure, or negative pressure. Engineered with the field proven Magnehelic gage movement, the A3002 provides a 0 2. 0" w. c. range with 2% full scale accuracy. This Photohelic pressure switch utilizes phototransistor actuated DPDT relays, ensuring chatter free
